So I was reading St. Basil's homily on fasting, and I got intrigued on a small part of the beginning of his homily. In context it says, "For, just as the tapeworms that breed in the intestines of children are obliterated by certain very pungent drugs, so also fasting--a remedy truly worthy of its appellation--when introduced into the soul, kills off the sin that lurks deep within it."
I was looking up the Greek word for fasting (nesteia), and saw that it was used for words like "fasting" and "hunger". I want to know if anyone has any idea what the appellation of "nesteia" was that St. Basil had in mind that made it "worthy".
